Simple Infinite Mob Spawn Hack For Leveling (Horde Only, Requires Automation) (Patreon)

(EDIT: some patreons expressed disappointment over the speed of this method: This is NOT a fast leveling method, it is solely for players using semi or full automation). 

This exploit is useful for automated or semi-afk leveling.

The Horde quest "Sludge Investigation" offered by Nozzlepot at Nozzelpot's  outpost in the Northern Barrens requires the player to investigate "Muddy Tracks" at the nearby Sludge Fens.

When you have completed this quest another one automatically ppens up entitled "Sludge Beast". This requires you to click on an underwater object  which produces a sludge beast. 

If you are in a party and convert it to a raid you can click on the object forever and produce endless sludge monsters, which are easy to kill and award normal experience. Each mob must be clicked before another can be created.

Although this is open world content, because the mob spawns underwater you are invisible to most players. It is desirable to have some form of water breathing as you will eventually drown if you stay underwater long enough. 

The Sludge Beast drops no loot, this is just for leveling. There are similar mobs which DO drop loot in the archives here.
